Case Type   : MOT支持的DDL
Case Name   : 结合MOT表，以START TRANSACTION启动事务以END结束事务测试
Create At   : 2020/09/18
Owner       : opentestcase001
Description :
    1.设置enable_incremental_checkpoint参数为off,并重启数据库
    2.开启事务,创建普通MOT行存表,插入数据,结束事务,清理数据
    3.恢复环境默认配置，修改enable_incremental_checkpoint为on，并重启数据库
Expect      :
    1.设置成功，重启数据库成功
    2.操作成功，清理数据成功
    3.修改参数成功，重启数据库成功
History     :
   modified by opentestcase010 at 2023/2/6，优化MOT用例
